Sigh...

The system that is adding the + is AR Cluster. 

However that is not the specific problem. Unfortunately there are many
people running "spot suckers" that are re-injecting the sucked spots
from the "user" format output of a node, without sufficient (sometimes:
no) checking. It could also be a artifact of continued clx use (probably
using a "passive" connection. 

It is (some of) these people that are causing the problem.

Yes and, as usual, it falls down to me to band aid the problem. 

Which I believe I have now done and put into CVS.
